Yep, we're still milking the original post from the opening of the Rockman Online blog. But this ought to be the finale, as we have detailed translations of the site's direct contents. This has all been translated by Ka-hun Yu, via the page 200 Percent Protagonist. Hit the jump for detailed info on the game's storyline, factions and player types. Be warned, it is quite a large block of text.
Thanks, Ka-hun Yu!

Plot:

PROLOGUE:

The birth of robots who look like humans, who think like humans, who feel emotions like humans…

Why did humanity create robots that resemble human beings?

One of their two creators, Dr. Light said, “Humanoids are the descendants of humanity. They are friends that will work together with us to create a more prosperous way of life.”

Their other creator, Dr. Wily said, “As god made man in his image, the birth of humanoids is simply humanity’s first step to becoming gods.”

The wars started from the two creators’ differences in ideals. Nobody ever expected them to rage on for the length of centuries without end.

Now, a new chapter begins in the history of these long wars, surpassing eras and generations!

The first post in the Hunter Intelligence Center, which, setting-wise, is being administrated by Alia. The UCA/URA post.

Thank you for visiting the Hunter Intelligence Center. I’m Alia, the leader of the operator team in charge of administrating the Hunter Intelligence Center. Pleased to Meet you.

The Hunter Intelligence Center was created to provide newly recruited Hunters as yourself with history, character biographies and combat data. Because there is a vast amount of important intel that has been gathered by the UCA, access to most files has been restricted from new recruits. As such, it may look significantly empty at the moment…

Because “Gaia” is a military complex that’s different from the era that most of you are from, I’m sure you all have a lot of questions. The operator team plans to periodically unlock access to the information you need to get used to life on Gaia, so please stop by regularly and check if there are any updates.

While you are primarily associated with the Irregular Hunters which were formed to protect mankind and repliroids from Irregular attacks, you are also associated with the UCA and are to engage combat with the Irregular forces, the URA. Today, we’ll introduce you to the the UCA.

UCA (United Continent Association)

The UCA was founded due to the need for a new organization for political, economic and military activity on a larger scale as national boundaries disappeared with the birth of a global government.

The UCA, founded by representatives with the most power from each administrative district(which are divided according to continent), is the most powerful organization on Earth, along with the global government.

As Irregular activity rose all across the world, the UCA determined that the global government’s large-scale army couldn’t efficiently respond to the skirmishes with the Irregulars and responded with troops of Irregular Hunters cloned from the DNA data of legendary Irregular Hunters from the past.

The UCA’s Irregular Hunters efficiently handled the Irregular outbreaks across the world and were acknowledged for their efforts. However, stronger Irregulars joined together and formed the the URA to counter the Irregular Hunters, and as a result the UCA also been criticized for providing the motivation behind the URA.

Iris and Colonel are the shadowed ? characters. Information on their types hasn’t yet been released.

URA (Ultimate Repliroid Association) [Translator's Note: I'm going by Repliroid because that's more in line with the "Rockman" naming scheme. Korea has a bit of an issue with consistency, sadly.]

The term Irregular is used to refer to Repliroids that act against the policies of the global government and Repliroid Union with war and acts of terror. While their activity has been constant, over the past few years it is widely believed that they have been effectively suppressed by the global government’s army and the UCA’s Irregular Hunters.

However, gathered by a common interest, the Irregular forces designated by the UCA gathered in secret to create the URA, an organization with the purpose of countering the global government and the UCA.

Those who seem to be Legendary Irregulars are at the center of the organization, similarly to the UCA’s Irregular Hunters, and through the URA’s well coordinated activity the global government and the UCA have lost control over a large number of areas. As the URA grows in size and becomes more organized, what used to be minor skirmishes have now grown into full-blown wars across the world.

According to recent intelligence from a UCA spy, behind the URA’s organized activity lies an important figure who seems to be involved with their origins.

[Translator's Note: As in, involved with how Irregulars came to be]

This concludes our introduction to the UCA and URA.

Recently, Gaia, the UCA military complex where new Hunters such as yourself were born, is also suffering casualties from the URA’s organized attacks. However, don’t worry, as countless Hunters who have inherited the will of past heroes are guarding this facility.

While it may be uncomfortable and difficult for now, us operators will continue to support you as much as we can until the day where you face off against the enemy as the UCA’s Irregular Hunters arrives. Please take care of yourselves until our next meeting.

I’m in charge of introducing you to the types of Repliroids, Irregulars, and techniques that you will encounter.

You’ve heard about how you were cloned from the DNA of legendary Repliroids from the past, correct?

I must warn you that the ones who completed legendary feats are those who provided their DNA to you, not you.

It would be helpful if you remembered that. On occasion there are those who foolishly rush towards the URA’s Irregulars as if they were legendary heroes.

Sigh… It’s a pain to clean up after their mistakes, so I request that you at the very least patiently hone your skills.

If you know your enemy and know yourself, you can win every battle.

Like that phrase, I’m here to inform you of your abilities and the Irregulars that you have to face.

Before we begin our lesson, to those of you who are giving dirty looks, some of you occasionally happen to act friendly for no reason at all. Well, if it’s a Zero Type I’ll let it pass, but keep in mind that I’m in charge of analyzing combat techniques and that I’m also your instructor.

You just might end up being unable to tell your control chip apart from everything else.

Well then, shall we have a look at the the DNA Type, “X”?

File Number RX1135

Accessing the DNA data for X.

Access Approved…

X is a legendary Irregular Hunter who worked to destroy the Sigma Virus, which causes destructive behavior in a repliroid, turning it into an Irregular.

He eventually won his battle against the Sigma Virus, and after confirming the world was in peace, went to eternal rest.

For ages, mankind and repliroids believed that the Sigma Virus had been completely eradicated.

Now, ages later where the Irregular Hunters’ battles remain as nothing more but a distant legend…

The Irregulars suddenly returned.

To stop the returning threat, the UCA cloned the heroes of the past.

The first to be copied was X, who brought forth numerous victories against the Irregulars.

The “X” that was born by cloning X’s DNA data is almost identical to the original X in appearance and ability, but lacks his memories, including combat techniques.

This X copy is a different entity from the X of the past, but people believe that like the X of the past it will be a beacon to bring hope to mankind and repliroids once more.

Combat capabilities

X-Buster

The X-Buster is X’s signature weapon. This high-energy weapon can fire multiple high-temperature plasma shots in rapid succession or charge to inflict large amounts of damage to the opponent. The X buster is equipped with a function that allows it to emulate the abilities of other repliroids by equipping their DNA chips, and the mystery behind this technology has yet to be solved even to this day.

The X-Buster is primarily for long-range battles, but it’s also a multi-purpose weapon that can handle close combat by copying the abilities of other repliroids.

X Armor

By equipping armors, X can carry out missions in various environments, including deepsea areas and hazardous rocky areas. The legendary armors that Dr. Light is said to have given to X have all been lost over the course of time. As a result, an armor researched developed by the UCA is currently being supplied.

Because Armor research requires a substantial amount of funding, Armors are only supplied to highly trained repliroids who are considered to be capable of using them efficiently.

Nova Strike

X has a special engine in his body that allows him to absorb external shock as energy and release it at a later time. Because a substantial amount of damage is required in order to gather enough energy to release, and all of it is drained upon release, it must be used with caution. At the same time, due to its destructive offensive capabilities X can use this to turn the tide against a stronger opponent.

As you can see from the DNA data, X Types specialize in long-range combat but can adapt to various situations by gaining enemy abilities and can overcome environmental obstacles with armors. In addition, there’s an additional fact that you must remember, even though it doesn’t appear in the DNA data.

X was originally classified as a B-Rank Hunter. Unlike other repliroids, he had the ability to “suffer”, which caused him to avoid conflict and limited his combat capabilities. However, the reason he was able to become a Special A-Rank Hunter and become a legend was that he was able to grow stronger due to his suffering, and that he had a heart of gold.

He always hesitated and was always worried, but once he made a decision he never turned back on it. I want you to think about that aspect of X in the slightest instead of just desiring power. A man who thinks long and hard before his conviction that always goes by his beliefs. Doesn’t that sound cool?

Well, let’s have a short break. Even if you guys don’t say anything, I can tell that your heads are hurting. Whew. In order to survive on Gaia, remember what I told you. If you become a Special A-Rank hunter later on, remember that it’s thanks to me. REMEMBER. Well then, goodbye~

Player: Zero Type

What do you think is the virtue of a good man?

Hmm? You want to hear what I think? Well, it’s nothing special.

Good looks are a given. Don’t you think it’s to support you even in silence, to always protect you by your side?

The legendary Irregular Hunter I’m about to introduce to you is that kind of guy.

You don’t need a long explanation for the best of them.

Well then, shall we have a look at the information for the DNA Type, “Zero”?

File Number RX0102

Accessing the DNA Data for Zero.

Access approved…

Zero is the masterpiece of Dr. Wily, who tried to use Humaroids (humanoid robots) to take over the world.

Zero is known to be the the original host of the Sigma Virus, which turns repliroids into Irregulars, and openly acknowledges that fact himself.

However, despite that dark past, Zero defeated countless irregulars with his undying belief in what’s right, and always trusted the sometimes unsure X, supporting him by his side.

Along with X, the UCA selected his greatest partner, this hero with undying courage as the best Hunter to defeat the Irregulars, and used all of their technology to successfully duplicate his highly-advanced body.

Hunters with the DNA Type “Zero” show the greatest compatibility with “X” Type Hunters, and can protect the long-range oriented “X” Type Hunters with their close-range techniques.

Combat Capabilities

Z-Saber

Zero originally used a Buster like X, but during the first of the Irregular Wars caused by Sigma, by giving his parts to X so that he could defeat Sigma, his buster functions become virtually useless. Because it was a weapon designed by Dr. Wily’s earlier technology, there was no means to repair it at the time, and thus he gained a new weapon, “Z-Saber”, a powerful beam sword.

He handled the Z-Saber using the full capabilities of his highly advanced body, and defeated many infamous Irregulars with his superior close-combat skills. The Z-Saber, which can now be called Zero’s trademark, became stronger after countless upgrades and Zero’s continuous training, eventually exceeding his Buster as an anti-Irregular weapon.

Zero Armor

Unlike X, Zero didn’t originally use an armor. However, the by utilizing the technology gathered from Zero’s DNA Data, the UCA has successfully created an armor that Zero Type Hunters can equip. The armor for Zero Type Hunters implements not only defensive abilities meant to increase survivability in close combat, but also enhances their offensive abilities to allow for the easier defeat of Irregulars.

Double Jump

Due to superior physical specs than X, Zero can jump an additional time in mid-air. By utilizing this ability, Zero can jump to higher places.

Most of you will probably have wished to have been born as Zero Type Hunters.

But in order to become like the real Zero, you need to put in a lot of effort and patience over a long period of time.

Since in addition to being naturally strong, he always tried his best to help his friend, X.

I’m overexaggerating? Hehe…

Doesn’t every woman have a knight in shining armor in their hearts?

I think I’ve said too much.

Well…Let’s rest for a while, and then go look at the DNA Types of other newly recruited Hunters

Player: Duo Type

Welcome. This time, we’re going to look at a different kind of guy from X and Zero.

There are probably some of you who have large chins that you can’t ignore even if you want to. We’re going to have a look at their DNA Data, the “Duo” Type.

Unlike the other Hunters, Duo’s not originally an Irregular Hunter.

He’s a lot older than X, so the UCA is pretty amazing. I don’t know where they got the DNA Data for a robot as old as him, but they managed to fully replicate him as you can see.

Duo’s a robot who made his appearance on Earth long before the free-willed repliroids appeared, but he’s said to have technology that’s even more advanced than today’s repliroids.

Shall I tell you why? That’s because he’s a robot from space.

You want me to stop joking? Then shall we have a look at the DNA Data?

File Number RC0158
Accessing DNA Data record for the Humaroid, Duo.
Access approved…

The specifics of Duo are top-class classifed information. This documentation’s purpose is to help the understanding of Hunters who interact with Duo-Type Hunters.

Warning: Hunters working together with Duo MUST be familiar with the contents of this documentation.

What you must always keep in mind is that Duo has complete immunity to the “Sigma Virus” which causes a fatal error in free-willed robots, and all other variations and similar viruses.

In addition, Duo Types have the ability to detect viruses or Irregulars with negative intent.

Because they can instantly tell whether or not somebody is lying, attempting to lie to or cheat a Duo Type Hunter is forbidden.

Warning: Duo Type Hunters are made to naturally eliminate evil. They will instinctively launch a punch at even the slightest little fib. Before lying, always be on the lookout for Duo Type Hunters. A single careless lie can cause both parties irreversible trauma.

Because of this, it is highly recommended that Duo-Type Hunters are dispatched if the area is contaminated by a virus or a reploid seems to be an Irregular.

Due to the crude exterior of Duo Types, they are often mistaken for old-generation robots.

Because of this, there are cases where technicians or reploids meant to service older robots are called in when a Duo Type is heavily injured. However, this is discourtesy towards them.

They have been developed with technology more complex than any repliroid, and there are only a select few who can understand and repair Duo Type Hunters.

As such, if a fatal flaw is discovered, we request that you immediately make an emergency communications link with UCA headquarters.

Warning: Contrary to their external appearances, Duo Type Hunters have an extremely intricate internal structure. Attempting repairs and check-ups without the proper qualifications is forbidden.

Currently, the UCA is doing extensive research on the repair of Duo Type units on the battlefield.

However, most Duo Type Hunters have advanced self-repair capabilities, and as thus repair most injuries using standard repair kits.

Combat Capabilities

Duo Knuckle
Duo doesn’t have any particular armaments. His primary weapon is his fist, which flows with mysterious energy. He grinds the opponent into dust by swinging his giant fist with force that befits his massive form.

Duo Armor

The UCA doesn’t have the proper technology necessary to develop an armor for Duo Type Hunters. However, this mysterious robot designed his own personal armor, which mimicks the armor technology of other Hunters. Duo Type Hunters are known to arm themselves with armors that fit their current experience and monetary deposits.

Flight

Duo can use use the rockets on his back to achieve flight for a short amount of time. Duo Types are capable of using this flight capacity to cross traps or pits more safely than other Hunters.

Reinforcement

Duo can use his mysterious energy to provide a protection effect or enhance offensive capabilities.

[Translator's Note: The target range is kinda unclear, but if it can help guys on the same map, it's gonna be a decent ability]

You can’t see anything about it being an alien robot?

Oh my, I forgot I have higher access than you.

I accidentally leaked classified information, so I’d appreciate it if you just forgot that bit.

It’s so preposterous that you can’t believe it? Well, if you hang around them for a while you’ll understand why I talked about Duo being an alien.

Oh, before you become friends with them, make sure to follow the guidelines.

There are a lot of guys who ignored the warnings and tried lying to them.

Be careful of what you say, take care, and let’s see each other again next time~
